With Rolex guarantee undated, GMT-Master presentation card, Bureaux Suisse de Contrôle Officiel de la Marche des Chronomètres Watch Rate Certificate No. 1609860 for movement no. 7/21009 dated 23 December 1964. Furthermore delivered with a fitted green presentation box and outer packaging.
The present watch is a fine example of an early GMT Master ref. 1675, featuring an appealing black lacquered dial and the pointed crown guards. Subsequently produced ref. 1675 models are fitted with the matte dial and show the rounded shoulders. For this reason, the present model is also known as the "Cornino" or "small horn" GMT Master.
It is furthermore a highly appealing example thanks to the original "small triangle" GMT-hand and all the original paperwork being still present. The bezel has, with time, developed from a standard "blue/red" color scheme to tones of coral-orange and light-electric blue. Examples of the famous 1675-series from the sixties are the perfect combination of vintage look with a lot of charisma and great daily wearability.
Due to the extraordinary success of the Rolex Sports models in the 1950s, it came to no surprise when the world's largest airline Pan Am commissioned a specially designed watch allowing their pilots to keep track of time in two locations.
With the beginning of transatlantic flights with jet aircrafts in 1956, travellers appreciated the fact that the journey times were reduced from 13 hours to 7 but suffered from new phenomena, the jet lag. Worried about the possible effects on their pilots and, after researches, Pan Am management advised them to keep on "home" time while away from base. As at the same time they needed to know the local time and consequently, a joint task force from Pan Am and Rolex was assigned. The team devised a watch with an additional hour hand, which revolved once every 24 hours and a rotating bezel marked with those same 24 hours. The model was named "G.M.T.-Master" after the world's standard time, the Greenwich Mean Time.
